## CAPI-STIS-Web ##
*CAPI-STIS-Web is an Enketo Express application development that aims to be a Web-based CAPI client application*
### Installation ###
*To use CAPI-STIS-Web, install Enketo Express and insert a folder from respository into the application*
*Installing an Enketo Express application can be followed in the following url:* https://blog.enketo.org/install-enketo-production-ubuntu/
Complete Installation Stages As Below:
**Installation on server (ubuntu-server)**
1. Install the first batch of software packages as follows and enter Y when asked to confirm :
```
sudo add-apt-repository -y ppa:chris-lea/redis-server
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install -y git nginx htop build-essential redis-server checkinstall python
```
1. Install NodeJS and global Node packages
```
curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
sudo apt-get install -y nodejs
sudo npm install -g grunt-cli pm2
```
1. Install Enketo Express
```
cd ~
git clone https://github.com/enketo/enketo-express.git
cd enketo-express
npm install --production
```
1. Configure Redis
Configure 2 redis instances that run on different ports :
```
sudo systemctl stop redis
sudo mv /etc/redis/redis.conf /etc/redis/redis-origin.conf
sudo cp ~/enketo-express/setup/redis/conf/redis-enketo-main.conf /etc/redis/
sudo cp ~/enketo-express/setup/redis/conf/redis-enketo-cache.conf /etc/redis/
sudo cp ~/enketo-express/setup/redis/systemd/system/* /etc/systemd/system/
```
Start the 2 redis instances :
```
sudo systemctl disable redis
sudo systemctl daemon-reload
sudo systemctl start redis@redis-enketo-main
sudo systemctl enable redis@redis-enketo-main
sudo systemctl start redis@redis-enketo-cache
sudo systemctl enable redis@redis-enketo-cache
```
Test: Redis database
```
redis-cli -p 6380
ping
exit
```
```
redis-cli -p 6379
ping
exit
```
The response to both tests should be: “PONG”.
1. Configure Enketo
```
cp ~/enketo-express/config/default-config.json ~/enketo-express/config/config.json
nano ~/enketo-express/config/config.json
```
The default configuration is almost functional. We just need to create a secret API key and encryption key. is easiest to just set the server url to "" for now. So the minimum configuration items to change are:
```javascript
{
...
"linked form and data server": {
"name": "My Aggregate",
"server url": "",
"api key": "EERTIUCJSHDGKHD234325",
...
},
"encryption key": "a34sgfj324113413y",
"less secure encryption key": "b542sdf32dabdery"
...
}
```
Build :
```
cd ~/enketo-express
grunt
```
1. Copy file from repository
1. Copy and replace files in the app-controller folder to enketo-express/app/controller directory
in web-authentication-controller.js
```
var odkurl = 'http://192.168.165.4:3000';
var odkrealm = ':ODK Aggregate VM 1.4.12.0:';
```
change the odkurl to your [ODK API] (https://git.stis.ac.id/14.7977/odk-api) ip address and change the realm accordingly
in web-request-controller.js
```
var odk_url = 'http://192.168.165.4';
var enketo_url = 'http://192.168.165.6:8005/api/v2/';
```
change the odk_url to your [ODK API] (https://git.stis.ac.id/14.7977/odk-api) ip address and change enketo_url to the enketo-express you've just installed
1. Copy and replace files in the app-views-web folder to enketo-express/app/views/web directory
1. Copy and replace files in the public-js folder to enketo-express/public/js directory
1. Copy and replace files in the public-web folder to enketo-express/public/web directory
